Abstract

A data interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range 'serial' type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Technology

In this disclosure, the present embodiment of the invention relates to the host device and the client Devices with a high data rate signal transmission or a digital signal transmission signal Protocol, the process and apparatus including integrated circuits and components. More specifically, the Company On the content relates to a technique that has an internal and an external device using low-power applications , High data rate transmission mechanism, the multimedia and other types of digital signals from the host Or the controller device to the client device, in order to show or display to the end user.

BACKGROUND

In recent years, computers, electronic products and various video game-related technologies (eg DVD, and HD-VCR) to obtain a significant progress, enabling such devices to End users still increasing resolution, video, video on demand and graphic images, Even including some types of text. These developments in turn requires a higher resolution power Child viewing device, such as high definition video monitors, HDTV monitors, or dedicated image Projection components. For example, the type of sound reproduction of the CD, DVD, and also has Other associated audio signal output device, the visible image with a high resolution of this or higher Combining quality audio data, so as to produce a more realistic end-users, richer Or more real multimedia experience. Also, have been developed, such as MP3 players Class high mobility, high-quality sound system and music transfer mechanisms to provide end-users Rendering pure audio. This has led to calls from the computer to the TV even such commercial electronic devices Prepared by the typical user, or top quality for high-quality output and is increasingly growing habits and The more desired quality or quality output. ...

In a typical video presentation scenario, involving electronic products, video data is generally used when the In previous techniques to tens of kilobits per second on the magnitude of the rate of transmission, the rate is Aptly called slow or medium speed. Then, the data stored in the cache, or temporary or Long-term memory devices, in order at a desired viewing device for delay (later) broadcast. For example, you can use a modem, or reside in other type of Internet connection settings Prepare a program on the computer, "pass" or use the Internet to send images to pick Can be used to receive or send performance data of the image digitally. Use with or without such Line modem, portable computers, wireless personal digital assistant (PDA) or wireless Telephones wireless devices can also be a similar transfer. ...

Once the data is received, the data is stored locally in a memory element, a circuit or a set Prepared, for example, stored in RAM or flash memory, but also stored in the internal or external Unit storage device, for example, the small size hard drives, for playback. According to the data and plots Image resolution, playback can quickly start or a long delay before rendering playback. Is That in certain cases that do not require large amounts of data or the use of a small image buffer Or a low-resolution image, the image presented to allow some degree of real-time playback, so by After a small delay, some of the content presented, and more content is still in the process of transmission Medium. Assuming any transmission link is interrupted or not being used from the relative Transport channel interference from other systems or users, then once started showing that transmission of In view of the end user device is appropriate (reasonably) transparent. Naturally, When multiple users share a communication path (for example, a wired Internet connection), the transfer Transmission may be interrupted, or slower than expected. ...

Once the data is transferred to the receiver such as a computer or other equipment and the like the " To "device, wherein the computer includes a storage mechanism such as memory, or magnetic or optical storage Components, the information will be decompressed (or a special decoder player), such as If necessary, decode, and based on the corresponding available presentation resolution and control elements of Appropriate presentation ready. For example, X × Y pixel screen resolution representation of a typical Computer video resolution is usually low to 480 × 640 pixels to 600 × 800 and then to 1024 × 1024, of course, as required or desired, may also have various other generally resolution. ...

A rate of 30 frames per second or sports type watch the video image, The amount of data required about 73.7 to 1,006 megabits of data per second (Mbps), or large About 9.21 to 125.75 megabytes per second (MBps). In addition, people may want to tone Frequency data and images presented together, such as multimedia presentation, or if you want the audio data as Independent high-resolution audio presentation, such as CD-quality music. Treatment can also be used to pay Interactive control for the additional signal or signals. Each of these options have increased More data to be transmitted. In addition, involving high-definition (HD) television and film recording Update transmission technology may add more data and control information. In any case, when People want to transmit high-quality end-user or high-resolution image data and high-quality audio Frequency information, or data signal to generate content-rich experience when rendering the components and configurations To provide a source of such data between a host device or the need to have a high data transfer rate of chain Road. ...

Typically, 115 kilobytes per second (KBps) or 920 kilobits per second (Kbps) of about The data rate can be handled by Modern serial interface. Other serial interface such as USB interface, Can support data transfer rates of up to 12MBps, and such as the use of electrical and electronic engineering Cheng Association (IEEE) 1394 standard kind of dedicated high-speed transmission is possible with 100 To 400MBps rate magnitude. However, these rates can not achieve the desired The high data rate, the desired aim of these rates for future wireless data can Equipment and services used to provide high resolution, rich output signal to drive it Portable video display or audio device. This includes commercial and other presents for the calculation of Machines, gaming devices. In addition, these interfaces require the use of a huge number of host or system And client software to work. Their software stack also produces a lot of unwanted open Pin, especially when considering the application of the mobile wireless device or a telephone in case more prominent. This device has a strict memory and power constraints, and already overburdened calculated to Force. In addition, some interface cable or the use of a large volume of complex connectors, for Height requirements and beautiful mobile applications, these cables are too bulky bulky, can not make Satisfactory, and these connectors complex and increases the cost, or the power is too great. ...

Some of the above interfaces, and other very high rate data systems / protocols or The fixed installation computer equipment associated with the transmission data transfer mechanism, the existence of the other A major flaw. In order to support the required data transfer rate, but also require considerable power Rate and / or work with a large current. Greatly reduces doing this technique is used for the elimination Costs are high mobility of product availability.

In order to create and efficiently utilize a new device interface, has been prepared using a low-power Signal to provide a high data transfer rate of a signal protocol and system architecture. The Association Proposed based on packet and common frame structure, or linked together to form a protocol structure for Pass preselected data sets or data types, and applied to the interface command or operating results Structure.

A. Overview

The MDDI link connection or via a communication device called the host and client, the Clients are usually referred certain types of display devices, but can also consider other outputs and Input device. When enabled by the host, the data from the host to the display along the forward transmission (called Forward business or a link), from the client to the host data transfer in the reverse direction (referred to as anti- Or a link to the business). Shown in Figure 3 illustrate the basic structure of these. In Figure 3, Host 202 using two-way communication channel 206 is connected with the client 204, the bidirectional communication through Including the forward link channel in accordance with the

reverse link

210, 208 and shown in the form. However, this These channels are formed by a common set of wires, wherein the set of common data transmission wires Can operate in both forward and reverse link between the effective switch. This can greatly reduce the number of wires Volume, immediately solves the mobile electronic devices such as low power environment for high-speed data The current method of sending one of many problems faced. ...

reverse link

Furthermore, the host computer as a host device or control element present in the variety of its It is widely used or planned commercial products, these products are needed between the client High-speed communications link. For example, a host may be used at a high rate from a video recording device to the deposit on Chu clients to transfer data to improve response or high-resolution large-screen to transfer data For rendering. With on-board inventory (onboard inventory) or a computing system and / or Other household devices Bluetooth connectivity appliances, such as refrigerators, when the Internet or Bluetooth connection The mode operation, having improved capability of the monitor, or computer, or Control systems (hosts) exist elsewhere in the room, when reducing the indoor display (Away Client) and a small keyboard or a scanner (client) connection needs. Overall, skills Field technician will understand that a variety of modern electronic equipment and appliances will benefit from using this Kinds of interfaces, and by use of the additional or existing connectors, or cable are available Limited number of conductors to achieve higher data rate transmission of information to renovate old equipment. ...

Meanwhile, the client 204 may include information presented to the end user or from the user Presenting information to the host various devices. For example, goggles or glasses into the miniature display , Embedded hat or helmet projection equipment, such as embedded windows or windscreen vehicle And even in a small glass screen hologram element, or to render high quality sound or music Various speakers, headphones or a stereo system. Other equipment includes a presentation will be presented Conference information or movies and television image projector or projection equipment. Another example is the use of the touch Board, or sensitive devices, voice recognition input devices, security scanners, and others can be Calls from the device or system user is passing a lot of information, in which the device or system users with From the user's touch and sound in addition to less than the actual "input." Furthermore, the calculation Machines and accessories vehicle accessories or desktop docking station (docking station) and wireless phones Holders can also be used as the end user or other equipment and devices interface devices, and Clients can use (such as a mouse to the output or input device) or a host to help transfer data, Particularly in relation to the case of high-speed networks. ...

The present invention can be MDD Interface and communication signal protocol to simplify the equipment (inside The external mode) by the host processor, controller, or circuit component (for example) and external devices or equipment Shell or structure of the interconnection between the monitor (called internal model) to reduce these connections The cost or complexity and associated power and control requirements or constraints of these connections, and And improve reliability, rather than connected to or to external components, equipment or devices (external Mode).

Using this interface structure for each signal the total data rate serial link Changed in several orders of magnitude, which allows the system designer to easily for cost or equipment, power Rate, implementation complexity and optimize the display update rate. MDDI property does not Dependent display or other presentation devices (target client) technology. Can be easily adjusted A data packet transmitted via the interface timing to suit the characteristics of a particular client, the client Machine such as a display device, sound system, memory and control elements, or to adapt the audio - visual Audio system features a combination of timing requirements. Although this allows the system to consume as little as possible Power, but it does not require a frame buffer to each client, so that at least a certain level Agreement with MDDI. ...

The MDD interface is conceived to be able to handle the communications and computer industry can find Somewhat different to at least four or more types of physical interfaces. These classes Type interface is simple labeled Type 1, Type 2, Type 3 Type 4, and of course the art technology Surgical staff can also according to the specific application for or relating to the industry and the application of other Mark or name. For example, simple audio systems use less sophisticated multimedia system connection, And can be variously cited as "channel" features and so on.

The Type 1 interface is configured as a 6-wire (6-wire) or other type of conductor or conductive Component interfaces that make it suitable for mobile or wireless phone, PDA, electronic Games such as a CD player or MP3 player, portable media players, as well as Similar device, or a similar type of technology used in consumer electronic equipment. In one embodiment, Example, a line is configured as 8 (wire) of the interface may be more suitable for a laptop count Computer, laptop or desktop personal computers and similar devices or applications, these devices do not Require fast data update, nor embedded MDDI link controller. This interface Type also through the use of additional wire Universal Serial Bus (USB) interface to distinguish this Interface type, which supports USB is ideal for most personal computers in common Existing operating system or software. ...

Type 1 passes an interface including a display, audio, control, and limited signaling information signals, And are used by the mobile client, or do not require high-resolution full-rate video data Client devices. 30fps plus 5.1 channel audio in the case of Type 1 interface can Easily support SVGA resolution, and in the minimum configuration, a total of only three lines Pair, two pairs for data transmission, one pair for power transmission. This type of interface is mainly used In a device such as a mobile wireless device, this device is not normally connected USB host-side Received and transmitted signals. In this configuration, the mobile wireless device is a MDDI host device Equipment, and serves as a host computer for controlling said communication link from the "master", which In the host typically sends data to the client (forward traffic or a link) for presentation, Displayed or played. ...

In this interface, sent to the client via a special command or packet type, the main The host machine to receive communication data from the client (reverse traffic or link), This allows a client account for a specified period of time continuing bus (link), and the number of According to a reverse packet sent to the host. These are shown in Figure 4, which is called encapsulation Packet packet type (to be discussed below) to support the transmission of the reverse link packet Transmission, to create the reverse link. Assigned to the host to poll the client when the data Interval determined in advance by the host, and the time interval is to be based on the application of each designated Requirements. In the absence of a USB port is used to send information from the client or the data, this Type of half-duplex bi-directional data transmission is particularly beneficial. ...

Typically, agreed through consultation maximum data rate that can be used by the MDDI use The protocol allows the

type

Will be called the least capable device capabilities or Were available features are used to set the link performance. Typically, if the host and client can Enough to use the type 2, type 3 or type 4 interface system, both also with Type 1 Interface to work. Then, the host's ability to determine the target client, and negotiated and agreed cut Change to or reconfigure operations to a type 2, type 3 or type 4 in a pattern, as long as It can be suitable for a particular application. ...

type

The system also can be used in one direction, a pattern used in the other direction Another mode is to transfer data. For example, you can type four interface mode is used at a high rate transmission Sending data to the monitor, keyboard, or from a pointing device such as a peripheral device to a host device When transferring data using the Type 1 mode. Ordinary skill in the art will appreciate that the host and Clients are able to pass the output data at different rates.

MDDI protocol users often can be "external" mode and the "internal" mode distinction Open. External mode describes the use of the protocols and interfaces to a host device connected External to the device and the distance of the device up to 2 meters clients. In this case, , The host can also send power to external clients, so that the two devices are easy in the mobile ring Work environment. Internal model describes a device contained within the same host and a client with Even, for example, in public housing or bracket or some structure. An example may be a non- Line telephone or other wireless equipment, or a portable computer or game equipment should be With, where the client is a display or display driver, or an input such as a keyboard or touch pad Equipment, or stereo system, and the host is the central controller, the graphics engine or CPU components. In contrast with the external mode applications, due to the internal model application client located very close to the main Place machine, so in this configuration is not usually required to connect the power supply to the client. ...

In Figures 5 and 6 are also described in the host and the display device, such as between clients via MDDI link or the physical conductors used to transmit signals. Figures 5 and 6 Shows for transferring data via MDDI main path or mechanism uses labeled MDDI_Data0 + / - and MDDI_Stb + / - of the data signal. Each of these signals are Via a wire pair in the cable to transmit a differential data signal voltage. For through said interface Send each one, MDDI_Data0 right or MDDI_Stb right exists only a transition. This is based on the voltage rather than on the current transmission mechanism, the quiescent current consumption is near zero. MDDI_Stb signal drives the host to the client monitor. ...

In addition to the data type of an interface, or a path other than type 2 interface also includes an attached Plus data or wires or paths, called MDDI_Data1 + / -. In addition to type 2 connection Those data port or path outside the Type 3 interface contains two additional data or letter Signal path, known as MDDI_Data2 + / -, and MDDI_Data3 + / -. In addition to Type 3 Interface Data or path outside the Type 4 interface contains four additional data or signal path, Are called: MDDI_Data4 + / -, MDDI_Data5 + / -, MDDI_Data6 + / -, and MDDI_Data7 + / -. In each of the above-mentioned interface configuration, the host can use pairs or Were designated as HOST_Pwr (host power supply) and HOST_Gnd (host ground) signal to Display to the client or to provide electricity. As will be discussed further, if necessary, When the interface is being used, "type" is used in wire than in other modes or store available In the wires, in some configurations MDDI_Data4 + / -, MDDI_Data5 + / -, MDDI_Data6 + / -, or MDDI_Data7 + / - conductors, can also be used for power transmission. While some applications are different, but the power transmission mode is usually used for the external and internal mold Type usually do not require power transmission. ...

It should also be noted that the transfer from the host HOST_Pwr / Gnd connection is usually Provided for the external mode. Internal applications or operating mode is usually directly from the client to the other Internal resources to take power, instead of using MDDI to control the power distribution, as for skills Of ordinary skill as apparent therefore not described in further detail here This distribution. However, as one of ordinary skill will appreciate, of course, be Via MDDI interface to allocate a certain power supply to facilitate such control, synchronization or mutual Even.

In addition to incorporating state machine for the link synchronization client interfaces, host and Client link controllers contain very similar functions. Accordingly, the present embodiment of the invention allows the Create a single controller design or circuit, and it can be configured as a host or client, which Conducive to the application, and in general, this can reduce the manufacturing link controller Costs. ...

A. Frame structure

Figure 7 illustrates a method for implementing the packet transmission in the forward link communication signal protocol or By the frame structure. Shown in Figure 7, the information or a combination of digital data packet known as a meta- Element (element). Then, a plurality of packets and are combined together to form a so-called "sub-frames", And a plurality of sub-frames and are combined together to form a "media" frame. In order to control the formation of frames And a transmission sub-frame, each sub-frame from a dedicated packet having a predetermined, the packet is called a sub-frame message Header packet (SHP).

Selection of the host device to transmit for a given data rate. The host device may group The maximum transmission capacity of the host, the host back from the information source (retrieve) data to And either the client or the data will be transmitted to the maximum capacity of the other devices, and dynamically change Change this rate.

Or can be designed with the MDDI or signaling protocol of the present invention the access to work Debit client device can be queried by the host to determine that the client can use Max or the current maximum data transmission rate, or can use the default slower minimum speed Rates and available data types and supported features. You can use this information to monitor energy Force Packet (DCP) to send, as will be further discussed. The client was Illustrates the interface device can be used with preselected minimum data rates, or at a minimum data rate Frequency range transmitted data or communicate with other devices, and the host will use this range Data rate within the query is executed in order to determine the full capabilities of the client device. ...

When the frame is not in the book (more) packet to be transmitted, or when the host can not Sufficient to keep (keep pace) forward link transmission rate of the selected data transmission rate When the host sends a packet padding. Since each sub-frame header packet from the sub-frame start So at the end of the previous sub-frame includes a sub-frame just before filling the grouping (probably padding Grouping). Carrying data packets in the lack of space in the case, padding packet is available Could be the last packet in a sub-frame, or in the immediately previous (next previous) subframe End and in the sub-frame header packet before. In the host device, the task is to control operation To ensure that the sub-frame for each packet to be transmitted in a subframe are retained there is enough space. Also, once the host device starts sending the data packet, the host must be able to successfully make the frame The size of the group within the full, and can not cause data underrun (under-run) case. ...

An aspect of the embodiment, the sub-frame transmission has two modes. One mode is week Period of sub-frame mode, or when the cyclical element (periodic timing epochs), for Transmitted live broadcast video and audio streams. In this mode, the handle frame length is defined as Nonzero. The second mode is asynchronous or aperiodic mode in which when there is new information, Only use frames to the bitmap data to the client. This mode is achieved by sub-sub-frame header Group handle frame length is set to zero to define. Using periodic mode, when the client and Forward link frame structure synchronization, you can start sub-frame packet reception. This corresponds as hereinafter The discussion of Figure 49 or Figure 63 a state diagram definition of "synchronization (in sync)" state. In asynchronous aperiodic sub-frame mode, the receipt of the first sub-frame header packet received after the start Close. ...

This measurement is inherently include line drivers and receivers, and Internet child There is a delay in the system. This measurement is used to set the above general description of the reverse link encapsulation of The steering group and the reverse link rate divisor delay parameters. When MDDI link for special The maximum speed given application, this packet is a most useful. You can type a pattern The lower data rate transmission packet, thereby increasing the range of round trip delay measurement is formed. The MDDI_Stb signal behavior is described as in the following fields to send all zero data: two protection Time, all zeros and measurement cycle. This is done so MDDI_Stb at half the data rate of turn Turn, so you can measure the cycle where the client will be used periodically when MDDI_Stb Minutes.

In one embodiment, the client through the client capability packet is usually a client characteristics Capability indicator field bits 18 to indicate support for the round trip delay measurement packet can Force. Recommends that all clients support round-trip delay measurements, but the host may also be based on the most Large cable delay and maximum delay of drivers and receivers to learn the worst-case round trip Schedule delay. Hosts can also advance in the internal mode for MDDI link round trip delay, This is because it is using the interface device known design elements (wire length, the circuit class Type and characteristics, etc.) of the one aspect.

Figure 34 shows a round trip delay measurement packet format. Shown in Figure 34, the One embodiment, the structure of this type of packet is a packet length, packet type, hClient ID, parameter CRC, guard time a measurement cycle, all zeros and protect time 2 Fields.

Figure 35 shows the round trip delay measurement packet when the event occurred during Sequence . In Figure 35 , the host sends the packet round trip delay measurements , which followed through There are all zero and the guard time a field parameter CRC and strobe appear to align fields is shown . In the packet reaches the client before the display device or processing circuit , the delay 3502 hair Health . When the client receives the packet , the client as accurately as possible to the actual measurement cycle The start time of transmission of the 0xff, 0xff, and 30 bytes of 0x0 pattern (pattern), Wherein the measurement cycle is started is determined by the client . Client begins sending this sequence The actual time from the point of view from the host of a delay measurement cycle begins . The base amount of delay This is used to pass the packet line drivers and receivers, and network subsystems ( electric Cables , wires ) the time it takes for transmission . For this mode from the client to send back Host, the amount of delay experienced a similar 3504 .

In order to accurately determine the signal to and from the client's round trip delay time, host Occurring after the commencement of the measurement cycle the forward link bit count the number of time periods, straight To detect 0xff, 0xff, 0x0, and 30 bytes at the beginning of the sequence is reached. This Information used to determine the round-trip signal is transmitted from the host to the client and the amount of time and then return. However After about half of this amount will be attributed to the arriving to the client generated unidirectional signal path Delay.

In the two guard time period, the host and client are driven to a logic zero line Level, in order to maintain MDDI_DATA line is defined by the state. In the two guard time During the host and the client makes MDDI_Data enable and disable time signal for any He effectively round trip delay time is active low.

2-byte CRC register data field contains data only for the register list of the CRC. If the CRC fails the check, then register data can still be used, but the CRC error Count is incremented.

D. Packet CRC

CRC fields appear at the end of the packet, the packet may appear in some of the more critical Parameters, these parameters have significantly larger data fields, thereby increasing the transmission period The possibility of errors. With two of the packet CRC field, a CRC is when only When used, CRC generation is the first CRC after being re-initialized, the number following a long According to the CRC calculation fields from the beginning of the parameters that affect the packet.

For packets containing multiple bit errors exist the possibility to generate the proper remote control of the CRC. There is a packet error is detected on the possibility of close to correct CRC contains large Is the error on very long packets case where 7.6 × 10^-6. By design, MDDI link Will have a very low or zero error rate. CRC is intended to monitor the link for normal conditions, Instead intended to detect errors on a specific group in order to determine whether the packet should be retransmitted.

In an exemplary embodiment, the CRC polynomial is calculated CRC-16 Or X16 + X15 + X2 + X0. Figure 36 illustrates the present invention may be used raw CRC Generator and verifier exemplary implementation 3600. In Figure 36, CRC register 3602 Is input to the transmission just Tx_MDDI_Data_Before_CRC (before sending the CRC The MDDI data) is a packet on the line before the first value is initialized to 0x0001, Then the first byte of the packet from the LSB is shifted into the register. It should be noted that this figure The register bits corresponding to the order of the polynomial used, rather than by the MDDI A bit position. CRC register is shifted along a more effective way, which makes the CRC bits 15 In MDDI CRC field bit position 0, CRC register bit 14 in MDDI CRC field bit position 1 and so on, until you reach the MDDI bit position 14. ...

When the CRC generator and checker 3600 is configured as a CRC checker when the Rx_MDDI_Data (receiving MDDI data) line up to receive CRC is input Multiplexers 3604 and NAND gate 3608, and the use or non-(NOR) gate 3610, Exclusive OR (XOR) gate 3612 and with (AND) gate 3614-by-bit CRC register with the hair Present value for comparison. If there are any errors, such as the output of the AND gate 3614, Then for each packet contains a CRC error, the output is connected through the door to the register 3614 The input register 3602, CRC increased once. It should be noted that, shown in Figure 36 is shown Exemplary circuit can be output for a given CHECK_CRC_NOW (now checksum CRC) window Within one or more of the CRC error signal (see Figure 37B). Thus, the CRC error Counters usually only active in each interval CHECK_CRC_NOW first CRC error count of cases. If the CRC generator is configured, then end with the packet Align the moment, the CRC according to the clock output from the CRC register. ...

E. Packet CRC error code override (overload)

Whenever the host and transfer data between the client only when the packet and the CRC, which does not Accommodate the error code. The only error is a loss of synchronization. Otherwise, the link must wait for the lack of Good data transmission path or pipeline and overtime, and then reset the link and continue Proceed. However, doing so is time-consuming and inefficient.

For one embodiment of the use, and has developed such a new technology, which stars Part of the group CRC error code used to transmit information. This is generally shown in Figure 65. Also That is, the data transmitted by the processing device processor or generate one or more error codes, Which indicates that the communication processing or links may appear in a particular predetermined errors or defects. Encounter Error, the CRC bits used to generate the packet and sends the appropriate error code. Will Is to say, the use of error codes needed to override or rewrite the CRC value, the required The error code can be at the receiving end is used to monitor the value of the CRC field error monitor or Verifier detected. CRC value for the error code and for some reason love match Conditions, the transmission error codes complement in order to prevent confusion. ...

This technique of overloading the CRC value provides a very fast system response error, while With a minimal amount of extra bits or fields.

Shown in Figure 66, using the error detector or detector module 6602 shows the CRC Rewrite mechanism or means 6600, which can be formed as previously described in other circuits or learn As part of the process for detecting errors within the communication link or the presence or appears. Can form A part or the use of other circuits such as a lookup table to store the pre-selected error messages Error code generator technology or module 6604 generates one or more error codes to Indicates that there has been detected a predetermined specific errors or defects. Easy to understand that,

Device

6602 and 6604 may be formed according to a single circuit or device, or as a For other known processors and elements are programmed as part of the sequence of steps. ...

The CRC value comparison shows the control or comparison module 6606, for checking a selected one Whether one or more error codes to be transmitted with the same value of the CRC. If it is, the use of generations Complement code generator or generation module or device to provide the complement of the error code, in order to avoid errors Code is mistaken for the original CRC pattern (pattern) or the value, so that the detection side Confuse or complicate the case. Then, the error code selector or select the module components or equipment Select the desired device 6610 insert or overwrite error code, or their respective complement, As the case may be. Error code CRC rewriter or rewrite mechanism or module 6612 is A device for receiving the data stream, packets, and the desired codes to be inserted, and the rewriting Corresponding or appropriate CRC values, in order to transfer the desired error codes to a receiving device. ...

Figure 67A and 67B is shown in greater detail in Figure 66 of the override mechanism to achieve the overall Handling implementation. In 67A, in step 6702, the communication data is detected during or To one or more errors, and in step 6704, select the error code to indicate that a Pieces. At the same time, or at the appropriate point calibration in step 6706 the CRC value to be replaced, and In step 6708 an error and needs to compare the code. As discussed earlier, Result of this comparison is to determine the required code or other representative value with the current CRC values are the same. If it is, then the process proceeds to step 6712, or the complement of said In some cases, according to the other representative values selected code to be inserted. Once in

step

6710 and 6714 will be inserted to determine what the error code or value, then choose this An appropriate code to insert. For clarity, these steps as a separate step Shown, but it usually presents an output based on the determination made in step 6708 a single selection. Finally, in step 6716, the CRC location override these appropriate values to serving as the Said process for packet transmitted together. ...

The packet reception side, as shown in Figure 67B, in step 6722 the monitoring packet CRC Values. Generally, the CRC value is determined by the system of one or more process monitoring, in order to determine If errors in data transfer has occurred, and determines whether the request is to re-transmit one or Multiple groups, or prohibiting further operations, etc., some of which have already been discussed above. As part of this monitor, the information can also be used with known or preselected error Yard or on behalf of value, and detects errors occur. Alternatively, you can achieve independence The error detection process and monitor. If, as there is a code, in step 6724 extract it or mark it for further processing. Can be determined in step 6726 This is the actual code or complement, in this case, the additional step 6728 is used to the State value is converted to the desired code value. In either case, in step 6730 final mention Take the code, complement, or other values can be used to recover from the transfer of the code has been detected What error occurs. ...

MDDI link can quickly go to sleep and wake up from sleep quickly. By the In MDDI link can very quickly awake again to use, thus allowing this response Xu communications systems and equipment MDDI link is often forced to sleep in order to reduce power consumption. In a Embodiment, when the external mode client first awakening from hibernation, it's about data Rate and so the strobe timing operation, where the strobe timing and 1Mbps Same rate, ie, MDDI_Stb corresponds to a rate of 500kHz flip. A Once the characteristics of the client host has been discovered or its characteristics have been passed to the host, then the main XTC machine from 1Mbps to be able to run the client at any speed between the maximum rate Rate wake links. Internal models clients can host and client sides can run Any rate awakening. This usually applies to internal mode client first wake up. ...

During Sleep, MDDI_Data and MDDI_Stb differential drive is a high Cross-resistance state disabled and all differential pairs in the differential voltage is zero voltage. In the Soviet Union from hibernation Awake during the pulse sequence used to detect the differential line receiver with intentional voltage offset. In One embodiment, the receiver logic 1 and logic 0 level threshold value is approximately between 125mV. This makes the undriven differential pair in the link will be considered during the wake sequence logic Zero level.

In order to enter the sleep state, the host at the link sent after the close grouping of the CRC 64 MDDI_Stb cycle. After disabling the host CRC in 15-56 MDDI_Stb week Period (including output disable propagation delay) within the scope of the host MDDI_Data0 output. Main Machine link down after packet CRC and in its wake-up sequence initiated before sending 64 MDDI_Stb cycle. In one embodiment, the host-initiated wake-up is defined as the host MDDI_Data0 reach a valid logic 1 level, and after the drive pulse on MDDI_Stb Must wait before 100 nanoseconds. In one embodiment, the client packet link closed After the CRC and in the waiting MDDI_Data0 driven to a logic one level in an attempt to wake up the main Machines need to wait until at least 60 MDDI_Stb cycles. ...

If MDDI_Stb active during sleep, although it is unlikely that What clients can only be driven to a logic 1 state MDDI_Data0 about 70 MDDI_Stb Period (60 to 80 range). This action allows the host to start and restart in the forward Link (208) the data on the client's business and asks the state.

The host must detect the request appeared and started pulse sequence, ie, first MDDI_Stb driven to a logic 0 level will be driven to a logic high up MDDI_Data0 At least 100nsec. Then, the flip MDDI_Stb while continuing the MDDI_Data0 Driven to a logic one level and sustained 150 MDDI_Stb cycles (in the range of 140-160 Surrounded) and MDDI_Data0 driven to a logic 0 level and lasted 50 MDDI_Stb Period (in the range 40 to 60). If the client is detected MDDI_Data0 Logic 1 state more than 80 MDDI_Stb cycles, then the client should send the service request Requirements. When the client detects MDDI_Data0 at a logic 1 level reached 60-80 MDDI_Stb period, then the client will search for the host MDDI_Data0 driven to a logic 0 level up to 50 MDDI_Stb cycle interval. The driver in the host MDDI_Data0 To a logic zero level and lasted 50 MDDI_Stb period of time, the host then began Sending packets on the link. The first packet is transmitted sub-frame header packet. In MDDI_Data0 at a logic 0 level up to 50 cycles of 40 MDDI_Stb cycle interval , The client began looking sub-frame header packet. The following further discussions with the sleep process and start Action sequences associated time interval selected properties and tolerances. (See the following Figure 68A- C) ...

Host can enable MDDI_Stb initiated by first wake up, and to simultaneously driven to Logic 0 level. Until pulses are output as described below, MDDI_Stb driver was only To a logic 1 level. In MDDI_Stb reach a valid logic 0 level, the host is enabled MDDI_Data0 and to simultaneously driven to a logic 1 level. As described until MDDI_Data0 is driven to a logic zero level and lasted 50 MDDI_Stb between pulses Every time, MDDI_Data0 it should be driven to a logic 0 level. Hosts should MDDI_Data0 reached a logic one level and then on the drive MDDI-Stb before the pulse, etc. Be at least 100 nanoseconds. When considering the worst-case output enable delay time and occurs when Order relation. This basically ensures that the client receives in its MDDI_Stb driven by a host-driven MDDI_Data0 logic one level on a sufficient wake-up time to fully enable the MDDI_Stb receiver. ...

Figure 38 shows a typical case of no competition service request event handling 3800 Examples of steps, which for convenience of description, letters A, B, C, D, E, F And G to mark the event. The process begins at point A, where the host to the client Device sends a link down packets in order to inform it of the link will be transformed into low-power sleep state State. In the next step, by disabling the drive and put MDDI_Stb MDDI_Data0 drive Is set to logic 0, the host computer enters a low-power sleep state, as indicated at point B. Through MDDI_Data0 high impedance bias network will be driven to logic 0 level. In certain time periods After the client by putting MDDI_Data0 driven to a logic one level to the host sends a service Request, as shown at point C. The host is still using a high-impedance bias network to Victoria Held (asserts) logic 0 level, but the client drive to force the line to enter the Logic 1 level. 50 microseconds, the host recognizes the service request pulse, and By enabling its drive to maintain a logic 1 in MDDI_Data0, such as point D in Fig. However After the client to stop trying to maintain the service request pulse of effort, and the client to Driver in a high-impedance state, such as point E in Fig. The drive to the host MDDI_Data0 And the logic 0 level for 50 microseconds, as shown at point F, and in accordance with MDDI_Data0 A logic 0 level consistent way to generate MDDI_Stb. Place in MDDI_Data0 At logic 0 level up to 40 MDDI_Stb cycles, the client started looking for sub-frame header Grouping. MDDI_Data0 placed in the logic 0 level and the micro-drive MDDI_Stb50 Seconds, the host begins by sending a sub-frame header packet transmission on the forward link number It is, as shown in point G. ...

Figure 39 described a similar example in which the link restart sequence has begun after the dimension Support (assert) the service request, and also uses the letters A, B, C, D, E, F and G to Mark said event. This represents a request from the client, or the signal is very close to the destruction of the pulse Sub-frame header packet worst case. The process begins at point A, then the host to the guest Client devices resend packets close the link, informing it that the link will transition to low-power off Sleep state. In the next step, said host by disabling the drive and put MDDI_Data0 MDDI_Stb drive is set to a logic 0 level, and enter a low-power sleep state, such as B Point below. As mentioned earlier, through a high impedance bias network will MDDI_Data0 driven logic Logic 0 level. After a time, the host drives the MDDI_Data0 to a logic 1 level and for 150 microseconds to start the link restart sequence, such as point C in Fig. In Link restart sequence after the start and after 50 microseconds before the display is maintained MDDI_Data0 is 1 to 70 microsecond duration, as shown at point D. When this Happens because the monitor needs to request services to the host and the host has not yet identified Start link restart sequence. Then, the client no longer trying to maintain the service request pulse, and The client to drive a high-impedance state, such as point E in Fig. Host continue to MDDI_Data0 driven to a logic 1 level. Host to MDDI_Data0 driven to a logic 0 Level and for 50 microseconds, as shown in point F, and in accordance with the logic on MDDI_Data0 Logic 0 level consistent way to generate MDDI_Stb. In the MDDI_Data0 maintained until Logic 0 level and the drive MDDI_Stb up to 50 microseconds after the host sends Start sub-frame header packet data transmission on the forward link, as shown in point G. ...

Based on the above discussion, it can be seen that: a part of the wake-up sequence, previously Solution involves enabling the host through two states. For the first state, the host of the MDDI_Data0 signal is driven high and sustained 150 microseconds, and then put the letter MDDI_Data0 No. driven low and sustained 50 microseconds, while activation MDDI_Stb line, and then began to pass MDDI packet transmission. MDDI apparatus and methods for the use of the available data rate, the This process can be well used to enhance the level of the prior art. However, as described above, to reduce The condition faster response time or select the next step or process (i.e., simplified or Component capabilities), the always requires a faster speed. ...

Applicants have discovered a new and innovative ways to wake processing and timing, in which the main Machine clock cycle-based timing signal flip (toggle). According to this configuration, The host at the beginning of the wake-up sequence MDDI_Data0 signal is driven high after the main Machines from 0-10 microseconds start flipping MDDI_Stb, and until the signal is driven low before Wait. In the wake-up sequence, the host flip MDDI_Stb, as if MDDI_Data0 Signal is always at a logic 0 level. Doing so effectively the concept of time from the client side to In addition, and for these cycles, the host computer 150 from the first two states and 50 microseconds Microsecond time period was changed to 150 for those clock cycles and 50 clock cycles. Period. ...

On the client side, and now, the client implementations can be calculated using the generated clock First, the data line is high, then low for the number of clock cycles. The driving state of the high number of According to the present line number of clock cycles required is 150, the driving state of the data line low Number of clock cycles is 50. This means that for the proper wake-up sequence, the client Should be in a high state of the data line is at least 150 consecutive clock cycles, and followed by With the data line in a low state of at least 50 consecutive clock cycles are counted. Once this Both conditions are met, the client can begin to search for the first sub-frame unique word. This An interrupt mode, the counter returns to the initial state as the basis, where the client again Looks for the data line is in a high state of the first 150 continuous clock cycles. ...

As previously discussed, the host-based wake-up from Sleep customers the invention Machine implementation, in addition to the clock rate is not mandatory outside starting at 1Mbps, very similar In the case of initial startup. Instead, the clock rate is set to re-rate from any previous New beginning, the previous rate of communication links into hibernation when the rate is active. As If the host starts transmitting strobe signal as described above, then the client should be able to re-pair data Line is in a high state of at least 150 consecutive clock cycles, and the data line is followed by Low state of at least 50 consecutive clock cycles are counted. Once these two pieces have been met Pieces, the client can begin to search for a unique word. ...

Client-based wake-up from Sleep client implementations of the invention way, except that it By allowing the client to start driving the data line, the similarity with the host-based wake. Client Machines can be the case in the absence of asynchronous clock drives the data line to wake up the host device. Once Host identifies the client to the data line is driven to a high state, it can begin its wake Sequence. Clients can start or during the course of its wake a host generated clock Counts the number of cycles. Once the number of clients in a high state of the data line connecting the 70 Continued clock cycle, it can stop the data line is driven high state. At this moment, the host It should have the data line is driven high state. Thus the data line client can in high State another 80 continuous clock cycles are counted, so that the data line is in a high state The clock period to 150, and thus can find the data line 50 is in a low state Clock cycles. Once you meet these three conditions, the client can begin to look for a unique word. ...

This awakening process has the advantage of a new way to achieve it does not require time measuring devices. Whether it is an oscillator, the capacitor discharge circuit, or other such known devices, the client This external device is no longer required to determine the start condition. When implemented on the client device control panel System, counters, etc., when doing so save money and circuit area. Although the main Machine, the machine may not be as beneficial as the client, but on the core circuit for ultra-high density Degree of logic (VHDL) concerned, this technology should also be able to simplify the host. Use several Data and strobe lines as the wakeup notification and measurement source of power consumption is very low because no To run any external circuitry core components to make it wait for host-based wake. The so Cycle or a number of clock cycles are exemplary, but also can use other cycles, Ordinary skill in the art are evident. ...

FIG. 68A shows the case where there is no competition host initiated wake typical office Examples of processing steps, which for convenience of description, but also letters A, B, C, D, E, F and G to mark said event. The process begins at point A, where the host to the client Send link close grouping machine equipment in order to inform it of the link will be transformed into low-power sleep State. In the next step, B point, the master flip (toggle) MDDI_Stb and sustained turn Turn about 64 cycles (depending on system design needs), in order to stop flip MDDI_Stb Before completion of the processing allows the client, the client device which stops the recovered clock. Main Machine initially put MDDI_Data0 set to logic 0 level, and then after the CRC, in 16 to 48 cycles range (typically comprises an output disable propagation delays) Disabled MDDI_Data0 output. This may require the CRC after 48 cycles, and for the next A stage (C) some time before, the client's MDDI_Data0 and MDDI_Stb The high-speed receiver placed in a low power state. Close grouping of the link after the first 48 of the CRC A MDDI_Stb cycles after the rising edge at any time, the client will be its MDDI_Stb MDDI_Data0 and the high-speed receiver in sleep. Suggested that, in Link down after the first packet CRC 64 MDDI_Stb cycles before the rising edge, Clients and their MDDI_Data0 MDDI_Stb the high-speed receiver in sleep. ...

After a certain period of time, and the host by enabling MDDI_Data0 MDDI_Stb driver output started at point D link restart sequence. The host of the MDDI_Data0 driven to a logic 1 level, and the MDDI_Stb driven to logic 0 Flat, and its duration with the driver fully enable their respective output that should be occupied by the time As long. These output reaches the desired level after the logic, and the drive MMDI_Stb on the pulse, the host usually wait about 200 nanoseconds. Thus, the client Machine has time to prepare to receive.

Figure 68B illustrates there is no competition in the case of a typical client at the start of the wake Examples of processing steps, which for convenience of description, but also letters A, B, C, D, E, F, G, H and I to mark said event. As mentioned above, the process begins at point A, The host sends the client link close grouping, informing it that the link will be transformed into low-power Rate state.

At point B, the host and the last flip flip MDDI_Stb 64 cycles (depending on the system Design needs), in order to allow complete stop before flipping MDDI_Stb client processes, This signal is used to stop the client device in a recovered clock. Host initially put MDDI_Data0 set to logic 0 level, and then after the CRC at 16-48 Cycles (including output disable propagation delays typically) range, disabling MDDI-Data0 Output. 48 after the CRC cycle, and in the next stage (C) of a previous , You need to put in the client MDDI_Stb MDDI_Data0 and high-speed receivers placed Low-power state.

MDDI_Data0 and MDDI_Stb by disabling the host controller driver and set The low power sleep state, the host at the point C, or step C into a low-power sleep state State. Can also need to set the MDDI_Stb driver to a logic 0 level (using a high Impedance of the bias network) or set to continue turning during sleep. Also in the client Low power levels hibernation.

After a certain period of time, the client and by enabling MDDI_Stb Receiver Enable MDDI_Stb receiver in an offset, starting at point D link restart sequence, to Will ensure that the host before the opening of its MDDI_Stb drive, in the client received MDDI_Stb version of the state is a logic 0 level. If necessary, the client may need to Slightly ahead of the enabled receivers enable the offset (offset), in order to ensure that the received valid The differential signal and the error signal is prevented. Clients to enable MDDI_Data0 drives, with When the MDDI_Data0 line driven to a logic 1 level. If the start offset and standard MDDI_Data0 differential receiver time of 200 nanoseconds, you can also enable MDDI_Data0 and MDDI_Stb. ...

When the host drive is enabled and MDDI_Data0 is driven to a logic 1 level, MDDI_Stb output pulse on the host and lasted 150 MDDI_Stb cycle duration Room, such as point F in Fig. When the client identify MDDI_Stb the first pulse, It disables its MDDI_Stb receiver offset (offset). Clients continue to MDDI_Data0 driven to a logic 1 level and the last 70 MDDI_Stb cycles, and At point G disable its MDDI_Data0 drive. Clients continue to drive MDDI_Data0 Scroll to the logic 1 level and lasted 80 additional MDDI_Stb pulse, and in point H will MDDI_Data0 driven to a logic zero level.

In an exemplary embodiment, the use of the data strobe signal or DATA-STB Format of non-zero (NRZ) format data is encoded, so will the clock information embedding The data and strobe signals. The clock can be used without a complex PLL case be Recovery. Data from the two-way differential link load, which is typically done using a wireline cable to achieve , Of course, as described above can also use other leads, printed circuit or transmission components. Selected Communication No. (STB) is only driven by the master of unidirectional links are hosted on. Whenever there is back Back (back-to-back) state, 0 or 1, the data line or the signal to maintain a constant When the strobe will value Flip (0 or 1). ...

Figure 40 graphically shows how to use the DATA-STB (data - Strobe) Code Code to transmit such bit is "1110001011" data sequence instance. In Figure 40, DATA (DATA) signal 4002 shown in the signal timing diagram of the top row, and the STB (Strobe) 4004 signal displayed on the second line, in accordance with appropriate needs (common starting point) every two Are aligned. As time goes on, when the DATA line 4002 (signal) appears on the status of Is changed, then the STB line 4004 (signal) maintains the previous state, thus, DATA Signal of the first '1 'state of the STB signal, the first '0' state is its Starting values are interrelated. However, if the DATA signal state level does not change, then What STB signal flip to the opposite state, i.e. in the present example for the '1 'state, as Figure 40 The DATA providing another '1 'as in the case. That is, each bit period in the DATA And STB between and only one change. Therefore, when the DATA signal stays at '1 ' When, STB signal is again changed, this time to '0 'and the DATA signal level change Becomes '0 ', STB to maintain this level. When the DATA signal remains at '1 ' STB signal flip to the opposite state, that in the current instance '1 ', as well as the DATA Signal change or remain level or value, STB signal hold or change, and so on. ...

In Figure 41, the transmission section 4100 and is used to generate an intermediate signal path via 4102 Original DATA and STB signal transmission, and receiving section for receiving the signal and the restored 4120 Complex data. Shown in Figure 41, from the host to transfer data to the client, the DATA signal Enter the number of two D-type flip-flop circuit elements 4104 and 4106, and the input clock signal In order to trigger the circuit. Then, using two differential line driver 4108 and 4110 (electrical Voltage mode) of the two flip-flop output (Q) were divided into MDDI_Data0 +, MDDI_Data0-and MDDI_Stb +, MDDI_Stb-signal differential pair. Three inputs with or (XNOR) gate, circuit, or logic element 4112 is connected to receive the DATA and two The output of flip-flops, and generates the data input to the second flip-flop providing an output, It then generates said second flip-flop MDDI_Stb +, MDDI_Stb-signal. For convenience, In XNOR gate drew an inverting bubble so that it effectively so that the resulting strobe No. inverted Q output of flip-flop. ...

In Figure 41 the receiving portion 4120, consists of two differential line receiver 4122 and 4124 Receiving each of the MDDI_Data0 +, MDDI_Data0-and MDDI_Stb +, MDDI_Stb-signal differential line receiver according to the differential signal generation single-ended output. Then, Amplifier output is input to the two-input exclusive-OR (XOR) gate circuits or logic element 4126 Each input of said logic element for generating a clock signal 4126. Said clock signal Number is used to trigger the two D-type flip-flop circuits 4128 and 4130 in each one of said D Type flip-flop circuit is used by the delay element 4132 receives the delayed version of the DATA signal, One of said D type flip-flop (4128) generates data '0 'values and the other (4130) Generate data '1 'values. The clock also has a separate output from the XOR logic. Since Clock information is assigned to the DATA and STB lines, so the signal transitions between states are Slower than half the clock rate. Since using the DATA and STB signal processing re-XOR Is clock, directly over a single dedicated data line to send the clock signal compared to the case System is actually allowed in the input data and the clock times between the amount of deviation. ...

Each differential pair is Lee With the transmitted signal cable or wire characteristic impedance parallel termination (parallel terminated)'s. Typically, all of the parallel termination resistors reside on the client device. This approximates forward traffic (from the host to send data to the client) the differential receiver, but its The cable or other conductors or transfer elements for driving the end of the reverse traffic (from the client Sends data to the host machine). For reverse traffic signal driven by the client, by the host at the The high-impedance receiver is reflected, and terminated at the client. As mentioned elsewhere, the reverse data Or via the reverse link data is greater than the round trip delay of the cable data rate reciprocal Rate transmitted or sent. The MDDI_Stb + and MDDI_Stb-wire or signal only by the host Driven. ...

A. Overview

Figure 43a, 43b and 43c respectively showing the steps and the signal level from the host or client Used in order to go to sleep (do not ask, expectations or in need of services) and for the client to obtain From the host service. In Figure 43a, 43b and 43c, there is shown the first part of the signal Shows a close link sent from the host group, and then use the data to a high-impedance bias circuit Line driven to a logic 0 state. Its drive has been disabled client or the host does not send the number of Data. Since the link down grouping during MDDI_Stb is active, so it can be at the bottom See MDDI_Stb signal lines in a series of strobe. When the host of the bias circuit and logic Logical drive to zero, once the end of the packet, the logic level becomes 0. This generation of Table final signal transferred from the host or from the host end of the service, and this may occur At any time in the past, and this is shown to be included in order to suspend services as well as in service prior Before the start of the signal state. If desired, such a signal can be sent just to Reset the communication link to the proper state without a host device has been reviewed by the The 'known' First communication. ...

As shown in Figure 43a, and closed for the link group as discussed above, in the low Power sleep mode, turn off the link packet fields of all zeros after the first of the last one 16 to 48 MDDI_Stb cycle or pulse start, MDDI_Data0 drive Is disabled and enters a high impedance state. For Type 2, Type 3 or Type 4 link, in MDDI_Data0 drive is disabled while, MDDI_Data1 to MDDI_DataPwr7 Signals are also placed in a high impedance state. In the all-zero field have been described in the definition of the link Turn off the MSB of the CRC field of the packet after 64 cycles (or, depending on system design Had hoped), MDDI_Stb flip, allowing the client to complete processing and customer Client orderly shutdown of the controller.

Send all zeros in the field, the host of the drive has been disabled MDDI_Data0 and MDDI_Stb , The host enters a low-power sleep state. Over time, enable MDDI_Data0 And MDDI_Stb line or drive output, the host began shown in Figure 43b and 43c chain Lu reboot sequence, and start flipping MDDI_Stb, as a host or client-initiated wakeup Part of the request. ...

As shown in Figure 43a, and closed for the link group as discussed above, in the low Power sleep mode, turn off the link packet fields of all zeros after the first of the last one 16 to 48 MDDI_Stb cycle or pulse start, MDDI_Data0 drive Is disabled and enters a high impedance state. For Type 2, Type 3 or Type 4 link, in MDDI_Data0 drive is disabled while, MDDI_Data1 to MDDI_DataPwr7 Signals are also placed in a high impedance state. In the all-zero field have been described in the definition of the link Turn off the MSB of the CRC field of the packet after 64 cycles (or, depending on system design Had hoped), MDDI_Stb flip, allowing the client to complete processing and customer Client orderly shutdown of the controller. A cycle is a low to high transition, followed by a High-to-low transition times, or a high-to-low transition, followed by a low to high transition. Send all zeros in the field, the host of the drive has been disabled MDDI_Data0 and MDDI_Stb , The host enters a low-power sleep state. Over time, enable MDDI_Data0 And MDDI_Stb line or drive output, the host began shown in Figure 43b and 43c chain Lu reboot sequence, and start flipping MDDI_Stb, as a host or client-initiated wakeup Part of the request. ..._{stb-data-enb1}, Start the service, or wake up from hibernation, during this time , The line is driven to a logic zero level until it is fully enabled and then enable it MDDI_Data0 drive so far. In MDDI_Data0 achieve a high level or logic 1 after (after Over the time period t_{client-startup}Occurs), the host will MDDI_Stb remain at logic zero level. In Time period t_{client-startup}End, the master flip MDDI_Stb signal or line. In the period t_restart-high, The host will MDDI_Data0 line driven high, that is the logic 1 level, while The client does not drive MDDI_Data0, and then, in the period t_restart-lowWithin the MDDI_Data0 line is driven low, the logic zero level. Thereafter, the first prior to the business and Sub-frame header packet to start with, then, prior to transmission to the business group. At time t_restart-towAnd subsequent sub-frame header packet period, MDDI_Stb signal is active.

As shown in Figure 43c, used for MDDI_Data0 and MDDI_Stb driver output The case where the signal is disabled after a period of time, by the host to enable its MDDI_Stb in the period before the drive t_{stb-data-enb1}MDDI_Stb receiver is enabled within Offset or output signal, the client issues a service request or wake up from sleep. Then, off Enable client drive its MDDI_Data0 duration period t_host-detectIn this period, Host starts MDDI_Stb before flipping, the line is driven to a logic zero level.

The host detects the request, may be required after a certain amount of time or , The period of time is expressed as "t_host-detect"Thereafter, the host will remain at logic MDDI_Stb Logic zero level of time period t_stb-startupTo make a response, then, the host time period t_restart-highWithin MDDI_Data0 driven to a logic 1 or high, which began with a link startup sequence Flip MDDI_Stb. When the client discovered MDDI_Stb a first pulse, it disables Its MDDI_Stb receiver offsets. Clients continue to be driven to logic MDDI_Data0 Logic 1 level or time period t_{client-detect}Until it detects the host driving the line so far. In At this moment, the client is no longer maintained (de-assert) the request and disable its MDDI_Data0 drives, so the output from the client also entered 0 logic level, the main Driver MDDI_Data0. As described above, the time period "t_restart-high", The host continues The MDDI_Data0 driven to a logic '1 'level, then, the host of the MDDI_Data0 Line drivers to low and continue to "t_restart-low"Time slot, then, the first forward traffic in Sub Frame header packet begins. In t_restart-lowTime period and the subsequent sub-frame header packet during MDDI_Stb signal is in the active state.

VIII. Link Control (link controller operation) is implemented

A. packet processor state machine

MDDI link via a packet transmitted or more typically at about the speed of 300Mbps Rates such as 400Mbps, is transmitted very quickly, of course, when required certainly can support Holding at a slower rate. For now you can buy the (economic) general purpose microprocessors, etc. Run, this type of bus or transfer link speed is too high even impossible to control. Accordingly, Used to implement this type of signal transmission is the use of the actual implementation programmable state Machines to parse the input packet stream to be transferred or redirected to produce them should go to the suitability When the audio - video subsystem grouping. Such devices are known in the art, and specifically the usual For a limited number of operations, functions, or the state of the circuit in order to achieve the desired speed Degrees or ultra-high-speed operation. ...

Can be universal controller, processor or processing elements is used more appropriately act on or Manipulates a lower speed requirements of certain information, such as control or status packets. Receive Those packets (control, status, or other pre-defined packets), the state machine should allow them Via the data buffer is transmitted to the processing element or the like general-purpose processors, which are capable of Operating said packet in order to provide the desired result (effect) while the audio and visual points Group is transferred to its proper destination for action. If in the future, created by micro-processing Control or other general purpose controllers, processors, or processing elements to achieve higher data rates Processing power, you can also use this device's software control to achieve the following discussion State or a state machine, such as the devices are usually stored in the memory element or medium Procedures. ...

In some embodiments, the general purpose processor function can use the processing power or more To achieve the rest of the cycle, the processing capability or an extra cycle of the application from the computer The microprocessor (CPU) or controller, processor, a digital signal processor (DSP), Dedicated circuit or a wireless device in an ASIC been found, its implementation in a manner very similar to the Some modems or the image processor in the use of computer CPU processing found in Ability to perform certain functions and reduce hardware complexity and costs. However, this week Or use of the shared processing speed will, the timing or the overall operation of such elements to bring Negative effects, so in many applications, dedicated circuits or elements better suited to this general office Management. ...

To be able to display (micro-display) viewed on the image data, or to reliably Receives all packets sent by the host device, the client signal processing and forward link through Road timing synchronization. That is, clients and customers to reach a signal circuitry in time base The last to be synchronized in order to properly perform signal processing. Illustrated in Figure 49 this can be achieved with The signal processing steps or step method to achieve high-level state diagram. 49 is shown in FIG. For the state machine 4900 may forward link synchronization "Status" is classified as a "asynchronous Frame Status "4904, two" acquire synchronization state "4902 and 4906, and three" Synchronization In the state, "4908,4910 and 4912. ...

As 4902 began steps or state shown in rendering device such as a display or the like By client machine to preselect the "non-synchronous (no sync)" state, the search and the detected The first sub-frame header packet in a unique word. It should be noted that this non-synchronized state that selection Type 1 interface or set a minimum communication "back (fall-back)" setting. When Found during the search of the unique words, the client saved subframe length field. In addressing this CRC bits first frame does not verify, or until you get up before synchronization check. As If this sub-frame length is zero, then sync process therefore proceeds to state 4904, Here marked "asynchronous frame (async frame)" state, which indicates that the same has not been achieved Step. In Figure 49, in this step of the process is marked as having cond3, or condition 3. Also, if the frame length is greater than zero, then the sync state processing proceeds to a state 4906, the The interface status is set to "find a sync frame." In Figure 49, the process of this A step marked as having cond5, or conditions 5. In addition, if the frame is longer than Frame zero, the state machine that determines a frame header packet and good CRC, then at Processing proceeds to the "found one sync frame" state. In Figure 49, the mark to meet cond 6, or conditions 6. ...

B. obtain time synchronization

The interface can be configured to determine the specific amount allowed before loss of synchronization of the "same Step Error ", and returns to the" non-synchronized frames "state in Figure 49, once the state machine has Been reached "Synchronization Status" and no errors are found, then it will continuously encounter cond1 Results, and remains in the "sync" state. However, upon detecting a cond2 A result, the processing procedure of the state changes to "a synchronization error (one-sync-error)" Status 4910. At this moment, if another process detects cond1 results, that What state machine returns to the "Sync" state, otherwise it encounters another cond2 results And moved to the "two synchronous error" state 4912. In addition, if cond1 occurs, So deal with the state machine returns to the "Sync" state. Otherwise, met another cond2, And the state machine returns to the "non-synchronous" state. Also be appreciated that, if the interface encounter "Link closed group", then this will make the link terminates data transmission and return to the "extraordinary Step frames "state, as nothing can synchronize like, in the state shown in Figure 49 In the figure, will be referred to conform cond4. ...

Sub-frame header packet of the sub-frame length can be set to zero to indicate that the link is connected Closed, and the MDD interface settings configured in idle or sleep state, the host Transmit only one sub-frame. In this case, the client detects the sub-frame header packet after Must immediately receive packets via a forward link, because the link is in transition to the idle state Before sending only one sub-frame. In normal or typical operations, the sub-frame length is non-zero , And clients deal only with the forward link packet, while the interface is in the system in Figure 49 A display to "sync" state those states. ...

To one or more embodiments, the recommended or understood, MDDI host Some additional steps should be performed to ensure that it stops forward link transmission into the low-power Mode or fully closed before the link MDDI reverse link is stable.

Such a question may arise: If the host uses the round trip delay measurement Value is incorrect, this may cause the back from the client receives all reverse the loss of data transmission Lost, even if the forward link appears to be good. When a client is not synchronized with the forward link, the Or, due to extreme changes in ambient temperature cause differential driver and receiver propagation delay Produce correspondingly large changes may affect the round trip delay, if the host sends the round trip delay measurement Volume group, this phenomenon occurs. Intermittent cable or connector contact failure may also So that the client is temporarily out of sync and then was re-synchronization, in the meantime, it may not receive Round trip delay measurement packet. Subsequent reverse link packet can not be properly host solution Yards. ...

Can be used to overcome these problems, a technique or embodiments is: the link in Sleep State before the host to ensure that the client and the forward link synchronization. If MDDI host can not To do this, or no such opportunity, for example, when it is empty or because the working Appears cables, conductors or connectors apart, disconnected or broken connections caused by link interruption or failure, Then, the host at the beginning of the round trip delay measurement process or transmit reverse link encapsulation grouping Former should first try to make sure the client is synchronized.

The host can observe the client sends the client request and the status of the CRC error packets Error count field, to determine the forward link integrity. Host requests the packet from the client. However, if there is a major link failure or disruption, this request will most likely not respond, Because the client can not correctly decode the packet, or may simply not be able to receive It. Using reverse link encapsulation packet sent to client requests and status packet for CRC Error count as the first integrity check requests, equivalent to the first spin. In addition, the main Machine can send a round trip delay measurement packet to confirm about the client to lose synchronization The assumption is valid. If the client does not make a round trip delay measurement packet response The host can draw conclusions out of sync client, then you can start to make it back in sync Treatment. ...

Once the host derived host could lose synchronization with the forward link conclusion it in the test Figure filler packets sent before any grouping except wait until the next sub-frame header. This The purpose of doing so, so that the client has enough time to detect or find a sub-frame header packet Contains a unique word. Thereafter, the host may assume that the client has reset itself since It is not found in the correct position unique word. At this moment, the host can be sub-frame header points Group, followed by a round trip delay measurement packet. If the client is still on the round trip delay Late measurement packet to make the right response, the host can repeat the resynchronization process. Correct Response, the client packet round trip delay measurements, the specified sequence back to the main Machine. If you do not receive the sequence, the receiving reverse link encapsulation packet data will be lost in the reverse Defeated. The continued failure of this nature may indicate that some of the other system errors, which must otherwise Resolved, so at this time is not a part of link synchronization. ...

In the MDDI link into hibernation, the host should perform the above link Fault detection and link re-synchronization procedure. This can usually be sure that the link is to restart later Is executed when the round trip delay measurement packet is successful. If the host is no reason to doubt the chain Lu fault, and the client reported on the reverse link encapsulation packet and zero forward link CRC Wrong correct response, then the host can assume that everything is working or functioning properly (for example, No link failures), and continue to power down / sleep process.

C. Initialization

As mentioned earlier, in the "Start", the host configuration for the forward link below the minimum to Seek or need to 1Mbps data rate, or rate of work on this, and For a given application is properly configured subframe length and medium frame rate. That is, the positive and negative chain Road use Type 1 interface to start working. When the host determine the client monitor (or other Type of client device) the ability or the required configuration, usually just temporary use These parameters. Said host computer via a forward link transmission or a transmission sub-frame header packet, then Followed by a reverse link encapsulation packet, the packet is the request flag bit is '0 'is set to value of one (1), to request the display or client capability packet to the client in response. Once the display Indicator in (or with) the forward link synchronization is acquired, it is through the reverse link or channel Send the client and the client requests ability grouping and status groupings. ...

In internal mode, the host can know in advance the client parameter without receiving passengers Client ability grouping. Can follow the link to the host and client can work in any data rate Rate restart. In many embodiments, a system designer may select the best achievable High data rate to initiate a link, to speed up the data transfer, but this is not necessary, and And in many cases do not need to use this method. For internal mode operation, in Restart from hibernation link use during strobe frequency rate usually associated with the expected Consistent.

D.CRC processing

For all packet types, packet processor state machine to ensure that the CRC is being Appropriate or proper control. When detecting CRC compare to generate one or more errors, CRC error counter is also increased, and in the sub-frame being processed at the beginning of each of said reset CRC counter.

E. Optional lose synchronization check

While the above series of steps or a state capable of generating higher data rate or throughput speed Degrees, but the applicant has been found: You can also use other alternative settings or conditions change Variable to effectively achieve even higher data rates or throughput, in which the client uses this These conditions are declared out of sync with the host. The new embodiment of the present invention has the same basic structure Structure, but change state conditions have changed. In addition, in order to achieve a new counter Help for sub-frame synchronization checks. Figure 63 shows with respect to the steps and conditions, the figure Shows a method for establishing the operation of the state machine or a series of states and conditions. In order to clear Chu, shows only "access synchronization state" and the "synchronization state" section. Further, since the The resulting state of the state machine itself is basically the same, they use the same encoding Number. However, changing the states (and the state machine operation) the conditions somewhat changed, therefore Of the two graphs are clear, all renumber (1,2,3,4,5 and 6 with respect to 61,62,63,64, and 65), in order to identify the differences. Since this discussion does not consider Consider the asynchronous frame state, so in this figure there is a state (4904) and the condition (6) is not Re-use. ...

In Figure 63, the system or client (for display or presentation) from the pre- "Non-synchronized" state in the state machine 4902 starts 5000, which is the same as Figure 49. From the non- 4902 to change the state of the synchronization condition the first state change is found in the synchronous mode condition 64 carried. Assumed subframe header CRC is also passed on the packet (qualified 61), the packet processor state machine can be changed to the synchronization state 4908. Synchronization error That is wrong condition 62 will allow the state machine switches to state 4910, and when the second occurrence of this Condition when the state switched to 4912. However, it has been found that any MDDI packet CRC Failure will allow the state machine out of sync in the 4908 state into a state of synchronization errors 4910. Any MDDI packet CRC failure would lead to yet another move to two simultaneous failures like State 4912. CRC value using the correct decoding packets will cause the state machine returns to the synchronization status State 4908. ...

This new interface implementation allows the MDD interface link to more quickly identify the synchronization Failure to more quickly recover from the same.

To make this system more robust, the client should also add or take advantage of the sub-frame count Makers. Thus, the unique word in the signal or there are expected to arrive, the client checks the unique word Existence. If the unique word does not occur at the correct time, the client can be more quickly To identify the synchronization fails has emerged, which identify the synchronization failure faster than it has to be Wait a few (in this case three) th packet time or cycle much faster, and wherein the packet Much larger than the subframe length. If the unique word does not appear that it tests, in other words, Timing is not correct, then the client immediately declare link loses synchronization, and moved to the extraordinary Step state. Check for the correct word appears only in the process adds to the state machine condition 65 (cond 65), indicating that the unique word is incorrect. If it is desired on the client receives the packet, but the sub-frame Do not match, then the client can immediately enter the asynchronous state 4902, saving wait A plurality of synchronization errors (condition 62) of the additional time, which is usually done by a plurality of error-

sync

4910 and 4912 while the state encountered. ...

This change with additional counter or clients to the core of the counting function pairs Frame length count. In one embodiment, the use of down counter function, if the counter expires, Interrupts the currently handling the transfer of any packet in order to check the sub-frame unique word. As an option Selection, the counter can count up to the count to the maximum or special Compared to the value set in this calibration value corresponds to the current packet time. This process is to protect passengers Client without the client is not received correctly decoding the packets particularly long length. If the child Frame length counter interrupts are being decoded some of the other packet, then the packet should Across the sub-frame boundary, it can determine the synchronization has been lost. ...

The state machine for each type of said received packet, it performs a specific process Step or series of steps to implement the interface operations. Usually listed in the following Table XII shows Exemplary process for processing the forward link packets.

Reducing the reverse link data rate X.

The inventors have observed that: for the host link controller can follow certain parameters special Be adjusted in the manner or the configuration in order to achieve maximum or more optimized (scale) reverse Link data rate, which is very much needed. For example, for transmitting reverse link encapsulation of Group during the reverse packet fields, MDDI_Stb signal to flip (toggle) Thereby half the forward link data rate of the data to generate a periodic clock. This happens MDDI_Data0 situation because if all zeros being sent, the said master link The controller generates signals corresponding to the MDDI_Data0 MDDI_Stb signal. MDDI_Stb The signal is sent from the host client, the client will generate the clock signal which is used to Transferred from the client reverse link data, reverse the data to be sent back to the host. Figure 50 shows Showing a system using the MDDI forward and reverse paths in the signal transmission and processing of Typically encountered delay. In Figure 50, the Stb + / - generation, cable transmission to the client, Client receivers, clock generation, signal clock, Data0 + / - generation, transmission cables to the main And host receiver stages of processing the vicinity, respectively showing a range of delay values, namely: 1.5 ns, 8.0 ns, 2.5 ns, 2.0 ns, 1.0 ns, 1.5 ns, 8.0 is satisfied Second and 2.5 nanoseconds. ...

It should be noted that the signal delay through said interface with the actual length of each of the special Given host - the client system or the hardware used varies. Although not required , But through the use of packet round trip delay measurement system to measure the actual delay Whereby the reverse rate divisor is set to an optimal value, for each system can usually perform better. Host can support relatively simple but a low speed operation of the basic data sampling, or may also support More complex but supports higher data rate reverse advanced data sampling. Similarly, consider the branch Both methods support the ability of clients. ...

Round trip delay measurement includes determining the detection field of the measurement cycle begins and the host Received from the client, 0xff, 0xff, 0x00 response sequence between the beginning of this time period The forward link data clock appears the number of intervals, or to count it. It should be noted Is possible to increase the measurement count is about a small portion of the previous forward link clock period, Receiving a response from the client. If this value is used to calculate the unmodified except reverse rate Number, then it will lead to unreliable data because the sampling and on the reverse link dislocations generated Wrong. Figure 51 illustrated in an example of this situation, which is shown graphically in accordance with the generation of Table hosts at MDDI_Data, the host at the MDDI_Stb, the forward-link data within the host Clock signal and a delay count. In Figure 51, the delay counter is coming from 6 to Before 7 clock cycles as part of the forward link, the client receives a response from the sequence. If the Delay is assumed to be 6, then the host will just shift after shift, or may reign among the anti- The data sampling. Doing so will cause the host at the sampling errors. For this reason, the measured delay Previously used to calculate the Reverse Rate Divisor, should normally be increased by 1. ...

For a given instance, it becomes:

If used for this example the round trip delay measurement result is 7 instead of 6, then Reverse rate divisor is equal to 4.

Said reverse link data from the master clock rising edge of the reverse link time sampled. Main Machine and client (display) are present in the counter or similar known circuit or device used To generate a reverse link clock. The counter is initialized so that the first clock on the reverse link Rising edge appears on the reverse link encapsulation packet fields reverse link packet at the beginning of the first one. Illustrated in FIG 52A used in the following examples given situation. The counter Each rising edge of the signal increases by 1 MDDI_Stb, and count the number increases until the reverse Encapsulated packet in the reverse link rate divisor parameter setting the count returns (wrap around) Zero. Since MDDI_Stb signal is half the rate of the forward link to the flip, so the anti- The link rate is half the rate of the forward link by dividing the reverse rate divisor. For example, if n The link rate is 200Mbps, while the reverse rate divisor is 4, then the reverse link data rate Rate can be expressed as: ...

\frac{1}{2} \cdot \frac{200 Mbps}{4} = 25 Mbps

Packet length = 1024 (0x0400) turned a length = 1

Packet Type = 65 (0x41) Steering 2 length = 1

Reverse link flag = 0 Reverse Rate Divisor = 2

Parameter CRC = 0xdb43 all zeroes is 0x00

Packet length and parameter data packets between CRC field is:

0x00，0x04，0x41，0x00，0x02，0x01，0x01，0x43，0xdb，0x00，……

Returned to the client from the first reverse link packet is a packet length and packet class 7 Type 70 client requests and status groupings. The packet from byte value 0x07, 0x00, 0x46, ...... and so begins. However, Figure 52 can be seen only the first byte (0x07). In the figure, the first time the mobile reverse-link packets of a reverse link clock cycles, In order to illustrate the actual reverse link delay. The host to the client for the round trip delay Zero ideal waveform shown as a dotted line trajectory.

Transfer parameter byte CRC field of MS, CRC is preceded by a packet type, and then Is all zeros fields. When data changes from the host level, strobe from the host everything from Change to zero, and return to the one to form a wider pulse. When the data becomes zero, strobe Higher rate switching signal, only the change in data on the line at the end of the alignment field Produced near the end of change. For the rest of the figure, since the data signal has a fixed 0 Or a level and continuing certain time period, so the strobe signal to the higher speed switching, And this shift falls pulse pattern (along) on.

Host reverse link clock is zero until the end of one cycle shift, then the Bell began to support the reverse link packet. Arrow in the lower part of the figure represents the data samples Moment, as seen from the rest of the disclosure as will be apparent. Being transmitted is shown The first byte of a packet field (in this case 11 million) after the beginning of the steering 1 Now, and the line level because the host drive is disabled and stable. The dotted line of the data signal As can be seen the first one transfer (passage) of the delay, and, as seen bits three To be.

As can be seen in Figure 53 based on the forward link data rate of the reverse rate divisor Code Type values. The actual Reverse Rate Divisor is the round-trip link measurement result as determined, In order to ensure proper reverse link operation. The first region 5302 corresponds to the safe operating area, The second region 5304 corresponds to the edge Performance area, and the third area 5306 not that big Settings to work correctly.

In the forward or reverse link use the interface type is set to any setting work For the time, the round trip delay measurement and Reverse Rate Divisor setting are the same, this is due to As they are not based on the actual clock period of bits transmitted or received and that Operation.

Typically, the maximum possible reverse rate divisor is the ability to interface with the Type I round trip Measurement packet sent in the measurement window to half the number of bits or, for this example:

May also be used an advanced reverse data sampling method as a bit in the reverse Smaller than the round trip delay between the choice. For this technique, the host simply measure the round trip Delay, but can determine the response from the client with a zero delay with respect to the client and Link "ideal" bit boundary phase. Know the phase response of the client device, the host Can determine a reverse data from the client safer sampled time. Round trip Delay measurement data to the client indicating the first phase reverse for reverse packet fields Starting position.

Figure 52B is a schematic diagram of advanced reverse data sampling is given an embodiment. Chart The round trip delay will have zero ideal reverse data signal waveform shown as a dotted line. 3.5 And 4 MDDI Stb cycles between the actual round trip delay can be observed as a solid line wave Shape, and a delay difference between the ideal waveform. This is a round trip delay measurement packet measurement The same delay, is equal to 7 forward-link bit times the round trip delay value measurement. In this Embodiment, reverse data bits are 2 MDDI_Stb Pulse length, that is, four forward link bit Time equivalent to a reverse rate divisor equal to 2. For advanced reverse data sampling, the With preselected reverse rate divisor 2, unlike other places that calculation it is very convenient. This seems to be the reverse data sampling for advanced basically the best choice, because the use of The traditional measurement described can easily determine the ideal sampling point. ...

Ideal reverse data sampling point can easily be as follows calculated: the Total round trip latency cue signal is divided by the forward position of each reverse link clock number or Each round trip delay reverse position to link the previous clock mode. Then, subtract 1 or 2, To get away from a security point of data conversion. In this example, 7 mod 4 = 3, so ,3-1 = 2, or 3-2 = 1. Safe sampling point is 1 or 2 forward link bit times from zero and from the Trip delay of the "ideal" bit boundary edge at the start. The figure shows the sampling points from the ideal position in Boundary of the two forward link bit times, such as in the timing diagram of a series of vertical arrows at the bottom of Head shows. The first sampling point is the round trip delay measurement after the first ideal bit boundary with safety Full sampling offset. In this case, the round trip delay measurement is 7, so the next processing Thought-bit boundary in the first eight bit times, then for safety sampling points plus 1 or 2, therefore, The first field of the data packet should be started in reverse after 9 or 10 forward link bit Between samples. ...

Reverse link encapsulation packet steering a field so that the host and client driver disabled Driver Enable time simultaneously. Round trip delay measurement time a packet protection Field so that the host and client functions overlap, so the client driver can drive in the host interface Actuator enabled before disabling. Reverse link encapsulation packet steering two fields so that the front of a field The data in the host driver before the opening can be sent from the client completely. Protection Between two fields provide a time value or cycle to allow the guest and host to the logical drive Logic zero level while driving. Guard Time 1 and Guard Time 2 fields are usually not adjusted Preset length or preselected length value to populate. According to the interface hardware is being used, you can make Using empirical data to obtain these values, and in some cases, they are adjusted to improve the operation. ...

Several factors contribute to determining the length of 1 turn, these factors are the forward link data Rate, the host drives MDDI_Data maximum disable time and client driver Enable time (usually the same time with the host disabled). Select the length of the field is turned to a 24 · t_BIT. (Table XI) 1 field in turn the number of bytes in length forward link interface type to use because Sub (InterfaceTypeFactor) determined and calculated using the following relationship:

Wherein the interface Type Factor is 1 for

Type

Maximum host drive Actuators enable time and client driver disable time is given. Round trip delay measurement Amount units is t_BIT. To turn to two the number of bytes the field forward link based on the specified minimum length Calculated the following relationship:

For example, the round trip delay of 10 clock forward link type three forward link communication Magnitude often used as steering 2 Delay:

XII. Optional reverse link timing

Although the use of the above-described timing and guard band (guard band) can realize a high data transmission Delivery rate interface, the present inventors have discovered a technique by changing the anti- The timing of discovery (reverse timing discovery) to provide shorter than the round trip time of the anti- To bits long.

As described above, the reverse link timing means is so configured previously, i.e., from the reverse Packet sequence last bit of Guard Time 1 starts counting the number of clock cycles until the IO The first one on the rising edge of the clock is sampled so far. This is used to give MDD interface output For the input and output timing clock signal. Thus, the reverse rate divisor is calculated by the following other Is given by:

Doing so provides a round trip delay is equal to the bit width, it is possible to get very available By the reverse link. However, has indicated that the reverse link can run faster, or to Higher data transfer rate operation, it is the inventor wants to use. The invention of new technology allows Xu additional capabilities using the interface to reach higher speeds.

This is accomplished by having the host counts the number of clock cycles until the completion of mining on a 1 Like to achieve, but in the reverse sequence packet, the host on both the rising and falling edges On the data line is sampled. Doing so allows the host to select the reverse position within the most useful and even the best mining Samples, to ensure that the bit is stable. That is, find the most useful or the best On the rising edge of the reverse reverse traffic data on the encapsulated packet is sampled. Optimum sampling Point depends on the reverse link divisor and the rising or falling edge detection to the first one. New The timing method allows the host only looking at the timing of the reverse link sent by the client within 0xFF 0xFF 0x00 model of the first edge, in order to determine the reverse encapsulated packet where mining Samples. ...

Illustrated in Figure 64 reaches the bit reverse position and how it will find a variety of reverse rate Examples of the divisor, and the guard time from the last bit of 1 beginning of clock cycles has occurred Projects. As can be seen in Figure 64, if the first edge occurs on the rising and falling edge (labeled as Rise / fall), between then for reverse rate divisor is an optimal sampling point, that is, the Optimal sampling point is marked as 'b' edge clock cycles, because it is the bit period of the reverse Only now rising. For the reverse rate divisor is 2, because the cycle along the 'c' Than 'b' along the closer position, the optimal sampling point clock cycle edge may still be 'b'. 4 for a reverse rate divisor is the case, the optimum sampling point may be clock cycle edge 'D', because it is closer to its value may have stabilized the trailing edge of a reverse position. ...

As can be seen, the optimal sampling point should be closest to the middle of the edge, so that with the The reverse rate divisor growing, optimal sampling point becomes easier to identify or select.

As can be seen, the optimal sampling point should be closest to the middle of the edge, so that with the The reverse rate divisor growing, optimal sampling point becomes easier to identify or select....

Once the host has chosen or to determine the number of clock cycles, it can use customer Machine to "investigate (explore)" a variety of reverse rate divisor to determine the specific reverse rate If you can use the divisor. The host (and client) can divide a start, and parity Received from the client's reverse state packet CRC, in order to determine whether the rate of the reverse Data can be transferred correctly. If the CRC is damaged, then there could be sampling errors, The host can increase the reverse rate divisor, and tried again to request status groupings. If the second Request packet is damaged, then the divisor can be increased again, and again requests. As If the packet is decoded correctly, then this reverse rate divisor can be used for all future Reverse grouping. ...

This method is effective and useful because since the initial round trip timing Estimates should not start reverse timing change. If the forward link is stable, so that So that there is no reverse link failure, the client should continue to decode forward link packets. Of course, Because this method does not ensure that the reverse link is desired, so set the link in the reverse link Road divisor is still the host duties. In addition, the divisor will depend primarily used to generate the IO The clock quality. If the clock has a large amount of jitter, then there sampling error Likely. This error probability as the round trip delay in the increase in the amount of clock cycles Plus increases. ...

This implementation seems best suited for the type 1 reverse data, but on the type 2 to 4 reverse data type may represent a problem, this is because the data between the lines Deviation may be too large, so that can not be optimized for only one data rate of operation of Above link. However, even with Type 2 through Type 4 for operation, the data rate Maybe not reduced to the previous method. If the method is repeated for each data line to select Choose the ideal or optimal clock sampling locations, then this method may work best for Purposes. If the data for each, they are in the same sampling time, then this Method can continue to work. If they are in a different sampling period, you can use the two Different ways. The first is for each data point to select the desired or more optimized sample Position, even if the data for each position of the sample and different purposes. Thus, the host computer Can set from said data bit is sampled after all reconstructed data streams: Classes Type 2 is two, Type 3 and Type 4 is four is eight. For hosts, another Option is to increase the reverse rate divisor, so that each pair of data in the same data bit Sampling clock edge. ...

Forward link MDDI_Data delay between pairs and MDDI_Stb deviation limits Maximum possible data rate, unless a delay offset compensation. Generation timing delay deviation The following summarizes the differences resulting from the controller logic, line drivers and receivers as well as cable and Connector.

A. The sequence of the link deviation limit (MDDI Type 1)

1 Type 1 link delay and deviation from the examples

Shown in Figure 57 is similar to Figure 41, Type 1 interface link to support the A typical interface circuit. In Figure 57, the MDDI Type 1 forward link of a plurality of processing Or interface level of each showing a propagation delay value and the deviation from the exemplary or typical values. The delay between MDDI_Stb and MDDI_Data0 causes the deviation of the output clock duty Ratio (duty-cycle) distorted. Use triggers 5728,5732 receiver trigger (RXFF) Level of the D input of the data change slightly after the clock edge, so that the data can be available Reliably sampled. The figure shows two

5732a and 5732b, their use of production This timing relationship born of two different problems to solve. In practical implementations, it can be Are combined into a single delay element. ...

cascaded delay lines

The total delay is usually obvious deviations occur or deviate from the sum of the following stages: a

5708,5710 The transmitter driver (TXDRVR); cable (CABLE) 5702; has a

receiver

5722, 5724 receiver line receiver (RXRCVR) and a receiver XOR logic (RXXOR). Delay 1 5732a should match or exceed the level of the XOR gate RXXOR The delay 5736, the following relationship can be determined by this delay:

t _{PD-min (delay 1)}≥t _PD-max(XOR)

Best to meet this requirement, so that the receiver the D input of flip-flop 5728,5732 Does not change its clock input before. If RXFF hold time is zero, then this is Valid.

Delay 2 (Delay2) the purpose or function is compensated according to the following relationship RXFF Triggers retention time:

t _{PD-min (delay -2)}＝t _H(RXFF)

In many systems, this value will be zero because the hold time is zero, in this case , The delay of the maximum delay of course 2 is also zero.

Receiver XOR stage deviations worst case is the data - late / Strobe - Early this situation State, in which the delay 1 is maximum, and the clock output from the XOR gate follows OFF Department arrive as early as possible:

t _{Off-max (RXXOR)}＝t _{PD-max(Delay1)}-t _PD-min(XOR)

In this case, the data in two bit period change between n and n +1, and the change Variable time very close to the bit n +1 is in accordance with the clock into the receiver trigger moment.

MDDI Type 1 link is the maximum data rate (minimum bit period) is a MDDI link Path through all drives, cables, and receivers and encounters set to the maximum offset plus RXFF level the totals of the function. Link RXRCVR stage output until the total Delay deviation can be expressed as:

t _{Deviation-max (LINK)}＝t _{Off-max (TXFF)}+t _{Off-max (TXDRVR)}+t _{Deviation-max (cable)}+t _{Off-max (RXRCVR)}

The "Cable" represent multiple conductors or lines and the corresponding interconnection or delays, and minimum Bit period is given by the following formula:

t _Bit-min＝t _{Deviation-max (Link)}+2·t _B-TP4+t _Asymmetry+t _{Off-max (RXXOR)}+t _jitter-host+ t _{PD-max(Delay2)}+t _SU(RXFF)

In the example shown in Figure 57, the external mode, t_{Deviation-max (Link)}= 1000psec, And the minimum bit period can be expressed as:

t _Bit-min= 1000 +2 · 125 +625 +125 +200 +0 +100 = 2300psec Or approximated as 434Mbps. In the example shown in Figure 57, the internal model, t_{Deviation-max (Link)}= 500psec, and the minimum bit period can be expressed as:

t _Bit-min= 500 +2 · 125 +625 +125 +200 +0 +100 = 1800psec Or approximated as 555Mbps.

In TXFF (5904), TXDRVR (5908), RXRCVCR (5922) and RXFF (5932,5928,5930) level in the use of additional dollars Member in order to support the additional signal processing. In Figure 59, the MDDI Type 2 forward link A plurality of processing or interface level of each showing a propagation delay and deviation values or exemplary Typical values. In addition to affecting the output clock duty cycle (duty-cycle) of MDDI_Stb and MDDI_Data0 delay between the deviation and, in the two signals and the other MDDI Deviation exists between the data signal.

5928 and 5930 triggered a receiver Device B (RXFFB) stage of the D input of the data change slightly after the clock edge, from And the data can be reliably sampled. If MDDI_Data1 than MDDI_Stb or MDDI_Data0 who arrive early, then MDDI_Data1 should be delayed so that at least in Delay deviation to right MDDI_Data1 sampled. To achieve these, the use of delay 3 (Delay3) delay line to delay data. If MDDI_Data1 than MDDI_Stb and MDDI_Data0 late, and it is also to delay by delaying 3, then MDDI_Data1 Change at the point to be moved closer to the next clock edge. This process determines the MDDI class Type 2, Type 3 or Type 4 Link data rate limit. Figure 60A, 60B and 60C Is shown in two data signals and MDDI_Stb with respect to each other or the timing deviation off Some examples of the Department of different possibilities. ...

On supporting types

flop

t _{PD-min(Delay3)}≥t _{Deviation-max (LINK)}+t _H(RXFFB)+t _PD-max(XOR)

Maximum link speed is determined by the minimum allowable bit period determined. When MDDI_DataX as possible Can arrive late, the speed of the most affected. In this case, the minimum allowable cycle time Is given by the following equation:

t _Bit-min＝t _{Deviation-max (LINK)}+t _{PD-max(Delay3)}+t _SU(RXFFB)-t _PD-min(XOR)Thus, the link speed limit:

t _{PD-max(Delay3)}＝t _{PD-min(Delay 3)}

And under the assumption:

t _{Bit-min (lower-bound)}＝2·t _{Deviation-max (LINK)}+t _PD-max(XOR)+t _SU(RXFFB)+t _H(RXFFB)

In the example given above, the lower limit of the minimum bit period is given by the following relationship:

t _{Bit-min (lower-bound)}= 2 * (125 +625 +200 1000 + 2 ·) = 5750 +1500 +100 +0 psec, which is approximately 174Mbps.

This ratio can be used for Type 1 link maximum data rate is much slower. MDDI automatic Delay deviate significantly reduced ability to compensate the delay deviation factor on the maximum link rate impact Only the valid data to establish the edges. MDDI_Data0 and MDDI_Stb calibration between Deviations are:

t _{SKEW-max(calibrated)}＝2·t _{TAP-SPACING-max}

And the minimum bit period are:

t _{BIT-min-calibrated}＝t _{SKEW-max(calibrated)}+2·t _B-TP4+t _Asymmetry+t _jitter-host+ t _{SKEW-max(RXAND+RXXOR)}+t _SU(RXFF)

Wherein, "TB" or t_BRepresentative from a bit boundary to minimum output level signal jitter. Merely indicates asymmetric internal delay differential receiver characteristics of asymmetry. "TP4" associated Or effectively defines for electrical characterization and testing purposes, as a client differential line driver And the receiver connection or interface (MDDI client controller device pin). For Remaining portion of the link system, which represents a convenient or a predetermined point, whereby the measurement and tables Sign signal delay. In one embodiment, the internal model, the parameters at the TP4 T_BThrough the relationship between the maximum value of t_{Differential-Skew-TP4-DRVR-EXT}＝0.3·t _BITDefined, for Clients transmitter's internal model, is t_{Differential-Skew-TP4-DRVR-INT}＝0.6·t _BIT; For client receiver external mode, it is t_{B-TP4-RCVR-EXT}＝0.051·t _BIT+175ps。

TP4 mark only for the interface and link the different test points (TP) to encode Number. In one embodiment, the internal mode and the external mode is defined as the same as the test point. There is a corresponding "TP0" test point for, or associated with a host controller MDDI Controller device connection or interface pins, the host contains a differential line drivers and receivers. In the present embodiment, the master receiver, with respect to an internal model, TP0 parameters at T_BThe maximum value from the relationship t_{B-TP0-RCVR-INT}＝0.051□t _BIT+50 Ps to define, for external mode, Relationship t_{B-TP0-RCVR-EXT}＝0.051□ _BIT+175 Ps; transmitter for a host, the relationship t_B-TP0＝0.102□t _BIT。

In the example given in Figure 59, t_{SKEW-max(Data0-Stb-Caliberated)}= 300psec, and the most Little bit period are:

t _{BIT-min-calibrated}= 300 +2 · 125 +625 +200 +175 +100 = 1650psec, which is about Is 606Mbps.

When MDDI_Data1 arrive as soon as possible, in order to reliably RXFFB data mining Sample, the associated programmable delay adjustment to the optimal setting, the precision is a tap, for safety Sake, adding additional tap delays. Maximum link speed depends on the minimum allowable bit Segments. When MDDI_Data1 as late arrival, the greatest impact. In this case, the minimum allowed Xu cycle time is:

t _{BIT-min-Data1-calibrated}＝2·t _{TAP-Spacing-max}+2·t _TA-TP4

Wherein, "TA" or t_ARepresentation from the bit to the middle cross-border signal jitter.

In the example given in Figure 59, based on sampling MDDI_Data1 minimum bit period The lower limit is:

t _{BIT-min-Data1-calibrated}＝2·150+2·125＝550psec

In one embodiment, the internal mode, the host delay deviation, delay Asymmetry and clock jitter typical total delay time is defined as:

t _{Asymmerty-TXFF}+t _{Asymmetry-TXDVR}+t _Skew-TXFF+t _Skew-TXDRVR+t _jitter-host＝ 0.467·(t _BIT-150ps)

For external modes are:

t _{Asymmerty-TXFF}+t _{Asymmetry-TXDVR}+t _Skew-TXFF+t _Skew-TXDRVR+t _jitter-host＝ 0.TBD·(t _BIT-150TBDps)

For the internal model, the client delay deviation, delay asymmetry and establish The typical total delay time time (t_B-TP4) Is defined as:

t _{Asymmerty-RXRCVR}+t _{Asymmetry-RXXOR}+t _Skew-RXRCVR+t _Skew-RXXOR+t _setup-RXFF＝ 0.307·(t _BIT-150ps)

For external mode, as follows:

t _{Asymmerty-RXRCVR}+t _{Asymmetry-RXXOR}+t _Skew-RXRCVR+t _Skew-RXXOR+t _setup-RXFF＝ 0.TBD·(t _BIT-TBDps)

Among them, the term is used in the future to be determined TBD values to maintain a flexible position mark, its Depends on a variety of external mode connection known characteristics and operational requirements.

XV. Operation

Figure 54A and 54B is shown an embodiment of the present invention interface operation during the And grouping data processing time for an overview of the general procedure, and 55 shown in FIG. Processing said packet of the interface device profile. In these drawings, the process in step 5402 Start, determine whether the client and the host communication path (here a cable) connection. This can be used by the host software or hardware to periodically poll carried out, the software, or Hardware for detecting the existence of the input of the host connector, the cable or the signal (e.g., USB interface), or which through other known techniques. Even if there is no client Connected to the host, then depending on the application, it can only go to a predetermined length of wait states, Into sleep mode, or inactive in order to wait for future use, which would require Farmers to take action to re-activate the host. For example, when the host resides on the type of computer equipment On, the user may have to click on the screen icon or request procedures, thereby activating the host processing To find clients. In addition, just insert the USB type connection can be activated host processing, It depends on the host or the resident's ability to host software and configuration. ...

Once the client and host, or vice versa, or the client is detected as present, Then at step 5404 and 5406, the client or the host sends the appropriate request service groupings. In step 5404, the client may send the client service request or status packet. Should note Meaning that, as mentioned above, the link may have previously turned off or is in sleep mode, So that a subsequent communication link may not be fully initialized. Once the communication link is synchronized, And the host attempts to communicate with the client, the client will also provide clients the ability to host sub- Group, as in step 5408. Hosts can now begin to determine the client can support support classes Type, including the transfer rate. ...

As previously mentioned, all data sent from the step 5412 is shown in a sub-frame header transmission of Group began, followed as shown in step 5414 the type of data being transmitted and padding points Group, where the data type is a video and audio stream packets. The audio and video data has been Ready or pre-mapped to the group, and if necessary or desired insert padding points Media groups to fill the frame number of bits required. If the host can send audio channel to enable the forward points Group grouping to activate sound equipment. Further, in step 5416, the host can use the Other packet types to send orders and information shown here as a color map, bit block transfer Or other packet transmission. Furthermore, the host and client can exchange packets using the appropriate Keyboard or the pointing device involves changing data. ...

During operation, a plurality of different events may occur, which will cause the host or client Machine requires different data rates or a different type of interface mode. For example, for the number of passes According to a computer or other device may process the data in the loading conditions encountered during (Loading conditions), the condition causes the packet preparation or slow down the rendering. A client to receive data from the dedicated AC power source may be replaced by a more limited battery power source, And in the limited power settings, it may not transmit data quickly and easily handle command So, you can not use the same resolution or color depth. Alternatively, the restrictions may be reduced Little or disappear, allowing the device to transfer data at higher rates. Which is even more need to make Request to change to a higher transfer rate mode. ...

Although it is not required to have a specific processing order, but the client and host can also post Conversion involves some data packet, the data is to be sent to the main connection with the client's finger Display device, keyboard, or other user type input devices, or received from these devices Data, of course, these elements may also be present on the host side. These groups usually pass Components rather than using the processor type state machine to process (5502). In addition, some of these life So also by the general-purpose processor (5504,5508) processing.

With respect to the previous host and client controllers discussed to drivers and receivers In the operation process in the transmission packet transmitted.

Processor and state machine provides the drive enable and disable control, as mentioned on Paul Guard time, etc., as discussed, in order to ensure the effective establishment or termination of communication link, and Transport packets.

XVI Display Frame Buffers

Compared with the computer graphics, video data caching requirements for moving video images is The same. Pixel data is often stored in the client's local frame buffer, so the client The images can be local refreshed.

Displaying full-motion video (frames per media almost every pixel in the display must be changed Becomes), the generally preferred stored in a frame buffer pixel data is input, and from The second frame buffer to refresh the image on the monitor. Can use two or more of the display buffer To eliminate the visual artifacts (visible artifact), as described below. When it has a frame buffer The entire image is received, the buffer can exchange roles, the latest map received As used to refresh the display, and the image is filled with the next frame buffer to another. Chart 88A illustrates this concept in which the display by the update bit is set to "01" to the Pixel data is written to the image buffer line. ...

Having a small video window in a fixed image of the application, the fixed image is written two Buffer (display update bit is equal to "11") is the easiest, as shown in Figure 88C and And subsequently updated through the monitor bit is set to "01" to write off slow motion image pixels Impulse control.

The following rules describe the useful manipulation of buffer pointers, while the new information is written off Client and refresh the display. There are three Buffer Pointer: current_fill (current fill) Pointed by the MDDI link is currently being filled with data buffer; just_filled (just Just fill) towards the nearest buffer is filled; being_displayed (being displayed) refers to Currently being used to refresh the display buffer. All three buffer pointer can contain from 0 to N-1 the values, where N is the number of display buffers, and N ≥ 2. Right buffer Pointer arithmetic is modulo N (mod N), for example, when N = 3 and current_fill = 2:00, increasing current_fill let current_fill is set to 0. In a simple situation of N = 2 Case, just_filled always current_fill's complement. MDDI medium frame at each side Boundaries (sub-frame count field sub-frame header packet is equal to zero) to execute the order specified As follows: the just_filled set equal current_fill, and set current_fill Equal current_fill +1. ...

MDDI video stream packets according to the following structure or method to update the buffer: When the display Update bit is equal to '01 ', the pixel data is written to the buffer specified by the current_fill; When the display update bit is equal to '00 ', the data is written to the pixel specified by the just_filled Buffer: When the display update bit is equal to "11", the pixel data is written to all buffers. Pointer to the buffer specified by the being_displayed to refresh the display. In the display refresh a A frame refresh yuan (epoch) after the last pixel and it starts the next frame refresh Refresh period before the first pixel, the display update processing is executed to being_refreshed (Refreshing) is set equal to just_filled operation. ...

When support video image, Figure 89 illustrate when the display update bit is equal to "01", and by MDDI link transmission from the video data, to a pair of the video frame buffer to the display Images. MDDI link is detected on the medium after the frame boundary, the frame currently being refreshed The refresh process is completed, the display refresh process will begin refreshing from the next frame buffer.

When support video image, Figure 89 illustrate when the display update bit is equal to "01", and by MDDI link transmission from the video data, to a pair of the video frame buffer to the display Images. MDDI link is detected on the medium after the frame boundary, the frame currently being refreshed The refresh process is completed, the display refresh process will begin refreshing from the next frame buffer....

Containing computer graphics and motion video image combined image, the video image Pixel data may occupy a small part of the media frames. In the display refresh operation and the image transfer involving phase The frame buffer with the case, it is very important. These conditions through Figure 91 of the Cross-hatched shading shows which reads from the buffer to refresh the display pixel can be Could be written into the buffer of the previous two pixels, or they may correspond to about to be written to the same A frame buffer.

The client using the three frame buffers to resolve small window frame buffer access competition Problem, as shown in Figure 92.

However, if the monitor refresh rate is less than MDDI link medium frame rate, So the problem persists, as shown in Figure 93.

Motion video images using a single buffer is much problem, as shown in Figure 94. When the Display refresh faster than the image transfer into the buffer, the image being refreshed sometimes will show positive An upper frame is written, and the image of the lower part is previously transmitted frames. When the monitor brush New faster than the image transfer (preferred mode of operation), the image showing a frame similar to the case of split Will occur more frequently.

XVII. Delay value table

Packet processing delay parameters grouped using a table lookup function to calculate the predicted delay to They deal with clients in some commands. Values in the table according to the number of ways to increase in order to provide Very wide dynamic range, delay value.

2-byte count field using color mapping project value to specify three - byte color map entry Total purposes, these items are included in the color mapping data field, or specify exists in this Color mapping data packets over the color map of the total number of table entries. In this embodiment, , The color map is the number of bytes of data in the color mapping project counts three times. Color mapping Shot item count is set to zero so as not to send the color mapping data. If the color mapping The size is zero, then the offset value is usually still color mapping sent, but ignored by display. Color mapping offset field (4 bytes) Specifies the color mapping data packet from the client Device color mapping table offset to start. ...

For the color map data fields, the width of each color map location is determined by the color Size field specifies the mapping entry, which in one embodiment, the first part specifies the number of blue Value, the second part specifies the green value and the third part specifies the red value. Color map size Field specifies the color mapping data fields exist in the three-byte color mapping table entries. If a single color map can not meet (fit into) video data format and color maps grouped Then you can send multiple packets to specify the entire color mapping, where each packet with There are different colors and color mapping data mapping offsets. Each data item in the blue color mapping, Green and red digits ability grouping should monitor RGB color map width field Is specified. ...

Each color mapping data items will be transferred in the following order: blue, green, red Colors, each component of the least significant bit is transmitted first. Each project will be a single red color map , Green, and blue components packaged, but each color map item (the blue component of the minimum Significant bit) should be based on byte aligned. Figure 100 illustrates a 6 blue, green, and 8 7 red color map data item instance. For this example, the color mapping points Group size is equal to 21 color map entry, and the client ability grouping RGB color map Width of the field is equal to 0x0786.

E. encapsulated packet on the reverse link

Parameter CRC field (2 bytes) contains the packet length from the length of all the words to the steering Section 16 CRC. If that fails the CRC check, the entire packet is discarded.

In one embodiment, the reverse link flags field (1 byte) contains request Information from the client a set of flags. If bit (e.g., bit 0) is set to a logic 1 Flat, then the host ability grouping using the client request specific information from the monitor, but if The bit is set to logic zero level, then the host does not need the information from the client. Position 0 is used to indicate when the host needs clients ability grouping, usually the client data points in reverse Group of fields in the packet sent to the host. Bit 1 is used to indicate when the host needs to client requests And status grouping of the data by the client in the reverse grouping field to send to the host.
